Mechanism choices and what they cost you
A confetti box is the lowest-margin mechanism — cheap to source, easy to rig, but looks modest on camera. A balloon pop (one giant 36" balloon stuffed with pink or blue confetti) is the mid-tier: $15-25 in materials, 20 minutes of prep, dramatic on video. Smoke cannons are the premium tier: $40-80 per cannon, require outdoor use or high-ventilation indoor space, and need a walk-through to confirm firing logistics. Price upward with mechanism complexity, and always charge separately for the device.
